> [22::53:26.100] unknown: KScreen::Output(448, "HDMI-0", connected disabled primary, pos: QPoint(0,0), res: QSize(-1, -1), modeId: "", scale: 1, clone: no, rotation: KScreen::Output::None, followPreferredMode: false)
This appears to be Bug 460341.

The remaining parts of the issue don't appear to be KScreen's fault, so I'm moving the bug report to KWin. Are you using the X11 session or the Wayland session? What GPU hardware and drivers are you using?

Comment 2 xbp 2022-11-13 17:47:08 UTC

I‘m using x11 session. I use a nvidia gpu rtx3060laptop and I am using the closed source driver provided in the AUR. The X11 configuration is default.

Comment 3 xbp 2022-11-13 17:53:57 UTC

Besides, if i use xrandr --output HDMI-0 --mode 3840x2160 and use the display configuration in the system settings ,it can work well until i shut it down or it sleeps automatically.
